Principle: no data = no claim (we do NOT declare "no restrictions" without a basis). 0 required / 12 items ### SDS (Safety Data Sheet) available - **fulfilled** (met / sds) - How to comply: Requirement: current SDS compliant with Reg. 1907/2006 (REACH) Annex II, 16-section format. - [Source / form](https://echa.europa.eu/information-on-chemicals) ### Compliant CLP label (pictograms + signal word + H/P) - **to be verified** (unknown / clp_label) - How to comply: No confirmed classification for this substance — the CLP labeling obligation CANNOT BE DETERMINED. Do not assume either an obligation or its absence: verify the supplier's self-classification and the entry in CLP Annex VI before placing on the market. - [Source / form](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32008R1272) ### Chemical OSH training (substance-specific) - **to be verified** (unknown / bhp_training) - How to comply: Laboratory staff: initial training (general induction + job-specific) + refresher training every 5 years (or every 3 for engineering/technical positions). Documentation kept in personnel files. - [Source / form](https://isap.sejm.gov.pl/isap.nsf/DocDetails.xsp?id=WDU20040180169) ### BDO registration (Polish Waste Database) - **to be verified** (unknown / bdo_registration) - How to comply: No confirmed hazard classification — the BDO status cannot be determined. Verify the CLP classification and the BDO obligation before disposal; do not assume there is no obligation. - [Source / form](https://bdo.mos.gov.pl/) ### ADR transport (international agreement) - **to be verified** (unknown / adr_transport) - How to comply: No ADR data in the MOL-GOD dataset for this CAS number. Do NOT assume there are no restrictions — before shipping, verify the transport classification in ADR 2025 (Table A) and in section 14 of the safety data sheet (SDS). - [Source / form](https://unece.org/transport/dangerous-goods/adr-2025-files) ### REACH registration (>1 t/year EU import) - **conditional** (conditional / reach_registration) - How to comply: Importers/manufacturers ≥1 tonne/year must register the substance with ECHA (technical dossier + Chemical Safety Report if ≥10 t). Check the ECHA Annex VI / registered substances list. - [Source / form](https://echa.europa.eu/regulations/reach/registration) ### SVHC notification (Substances of Very High Concern) - **to be verified** (unknown / svhc_declaration) - How to comply: SVHC status not verified against the available dataset — check the current ECHA candidate list; do not assume the absence of an entry. - [Source / form](https://echa.europa.eu/candidate-list-table) ### REACH Annex XIV (authorisation list) - **to be verified** (unknown / reach_annex_xiv) - How to comply: Not verified against the ECHA Authorisation List — check REACH Annex XIV. - [Source / form](https://echa.europa.eu/authorisation-list) ### REACH Annex XVII (use/marketing restrictions) - **to be verified** (unknown / reach_annex_xvii) - How to comply: No entry in the harmonised classification dataset (CLP Annex VI) for this CAS number — status of entries 28–30 (CMR ban) NOT VERIFIED; do not assume the restriction does not apply. The dataset of Annex XVII restrictions is also incomplete — check the consolidated Annex XVII and the harmonised CMR classification on the ECHA website. - [Source / form](https://echa.europa.eu/substances-restricted-under-reach) ### OEL — Occupational Exposure Limit in the working environment - **to be verified** (unknown / nds_workplace) - How to comply: No NDS data in the MOL-GOD dataset (incomplete set — ~41 of ~600 substances in the list). Absence does NOT mean there is no NDS — check the full list in Dz.U. 2024 poz. 1017 (Regulation of the Ministry of Family and Social Policy of 4 September 2024), and where none exists apply the OEL from EU directives or values recommended by NIOSH/ACGIH. - [Source / form](https://isap.sejm.gov.pl/isap.nsf/DocDetails.xsp?id=WDU20240001017) ### GIS register (precursors / psychotropics) - **to be verified** (unknown / gis_register) - How to comply: Does not appear in the available working set of precursors (list incomplete). Absence is NOT a confirmation — verify against Annex I of Reg. (EC) 273/2004 and the GIS list before placing on the market. - [Source / form](https://www.gov.pl/web/gis) ### Safety Data Sheet in Polish - **fulfilled** (met / sds_pl) - How to comply: Requirement: SDS in Polish for trade in PL (Art. 31 REACH + Chemical Substances Act Art. 17). - [Source / form](https://isap.sejm.gov.pl/isap.nsf/DocDetails.xsp?id=WDU20012112135) ## Data sources - [PubChem CID 93115](https://pubchem.ncbi.nlm.nih.gov/compound/93115) - [Wikidata](https://www.wikidata.org/wiki/Q27264187) - [NIST WebBook](https://webbook.nist.gov/cgi/cbook.cgi?ID=27676-62-6) - [ChEMBL](https://www.ebi.ac.uk/chembl/g/#search_results/all/query=27676-62-6) --- *Last updated: 2026-10-17 · Generator: MOL-GOD v3.12.33*
