2-(Chloromethyl)-5-methoxy-1,3,4-thiadiazole 2345AE 3914-44-1 C4H5ClN2OS CAS 3914-44-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Chloromethyl)-5-methoxy-1,3,4-thiadiazole 2345AE 3914-44-1 C4H5ClN2OS.

2-(Chloromethyl)-5-methoxy-1,3,4-thiadiazole 2345AE 3914-44-1 C4H5ClN2OS (CAS 3914-44-1) is a high-purity analytical reference standard with the molecular formula C4H5ClN2OS and a molecular weight of 164.61 g/mol.

2-(Chloromethyl)-5-methoxy-1,3,4-thiadiazole 2345AE 3914-44-1 C4H5ClN2OS (C4H5ClN2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
