Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1h-1,3-Benzodiazol-2-ylmethanethiol hydrochloride.
1h-1,3-Benzodiazol-2-ylmethanethiol hydrochloride (CAS 3020-65-3), molecular formula C8H8N2SHCl and molecular weight 200.68 g/mol, is a CATO reference standard with documented purity and traceability.
1h-1,3-Benzodiazol-2-ylmethanethiol hydrochloride (C8H8N2SHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
