Guanidine bromide CAS 19244-98-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Guanidine bromide.

CATO supplies Guanidine bromide (CAS 19244-98-5), a certified reference material (molecular formula HBrCH5N3, MW 139.98 g/mol) for analytical method development and quality control.

Owing to bromine substitution, Guanidine bromide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.98 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.

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.

As a certified reference material (CRM), Guanidine bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
