TESTING SYSTEM

Quality Testing System

Comprehensive analytical platform ensuring product quality meets research-grade standards across multiple dimensions

HPLC Purity Analysis

Reverse-phase HPLC (RP-HPLC) using C18 column with acetonitrile/water gradient elution. Detection at 214nm and 280nm for precise purity and impurity profiling.

Standard: Purity ≥ 95% (standard) / ≥ 98% (high-purity) / ≥ 99% (ultra-pure)

Mass Spectrometry (MW Confirmation)

ESI-LC-MS/MS or MALDI-TOF for precise molecular weight determination, confirming the synthesized product matches the theoretical value within tolerance.

Standard: MW deviation < 0.1%

Amino Acid Sequence Verification

Edman degradation or MS/MS fragment ion analysis for N-terminal and full-sequence verification, ensuring 100% match with the target sequence.

Standard: Sequence coverage 100%

Moisture Content

Karl Fischer titration to determine water content, evaluating product stability and storage condition requirements.

Standard: Moisture content < 5%

Residual Solvents

GC-MS detection of organic solvent residuals (DMF, DCM, acetonitrile, etc.) used during synthesis to ensure product safety.

Standard: Compliant with ICH Q3C

Appearance & Solubility

Visual inspection of appearance (white/off-white powder) and solubility testing in water, DMSO, acetonitrile, and other common solvents with usage recommendations.

Standard: White to off-white powder
