Chemical Structure
Description
The occurrence of 3-[(methylsulfanyl)methyl]pyrrolidine hydrochloride is closely related to sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-[(methylsulfanyl)methyl]pyrrolidine hydrochloride (CAS 1333729-77-3), molecular formula C6H13NSHCl and molecular weight 167.69 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, chlorine substitution, 3-[(methylsulfanyl)methyl]pyrrolidine hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
