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 1-(Thiophen-2-ylmethyl)guanidine.
1-(Thiophen-2-ylmethyl)guanidine (CAS 81882-12-4), molecular formula C6H9N3S and molecular weight 155.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 1-(Thiophen-2-ylmethyl)guanidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
