Chemical Structure
Description
CATO supplies pTH-Related Protein (1-16) (human, mouse, rat) (H-6575.0500) (CAS 126391-27-3), a certified reference material (molecular formula C77H128N24O25, MW 1789.99 g/mol) for analytical method development and quality control.
pTH-Related Protein (1-16) (human, mouse, rat) (H-6575.0500) (C77H128N24O25) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), pTH-Related Protein (1-16) (human, mouse, rat) (H-6575.0500) 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.
