Context
Why It Matters for Your Research
Why HPLC-MS Outperforms HPLC Alone
HPLC measures chromatographic purity but cannot confirm molecular identity. Mass spectrometry adds exact mass confirmation, detecting co-eluting impurities that HPLC alone misses. Dual-method verification is the USP-referenced standard for definitive compound identification.
Why US Manufacturing Matters
US-based cGMP facilities operate under FDA-inspected quality systems with documented SOPs, environmental controls, and batch records. Mixed sourcing introduces variability in regulatory oversight and documentation traceability across supply chain partners.
Why Batch Freshness Matters
Lyophilized compounds begin slow degradation from the moment of synthesis. Fresher batches mean higher starting purity and longer effective shelf life. A 14-day synthesis-to-ship window minimizes time-dependent degradation before the compound reaches your lab.
