( inverted exclamation markA)-6-Methyl-5,6,7,8-tetrahydropterine dihydrochloride 6-MPH4 69113-63-9 DL-2-Amino-4-hydroxy-6-methyl-5,6,7,8-tetrahydropteridine dihydrochloride (CAS 69113-63-9) is a high-purity analytical reference standard with the molecular formula C7H11N5OHCl and a molecular weight of 217.66 g/mol.
( inverted exclamation markA)-6-Methyl-5,6,7,8-tetrahydropterine dihydrochloride 6-MPH4 69113-63-9 DL-2-Amino-4-hydroxy-6-methyl-5,6,7,8-tetrahydropteridine dihydrochloride (C7H11N5OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
