FAQ

Cytidine 5′-Diphosphate Disodium Salt (CDP-Na₂) – Frequently Asked Questions

Q1: What is the main industrial application of cytidine 5′-diphosphate disodium salt?

Its largest commercial use is as the core synthetic intermediate of citicoline (CDP-choline), a mainstream brain metabolism therapeutic drug widely used for cerebral infarction and brain trauma recovery.

Other applications include: Specific substrate for CDP kinase and ribonucleotide reductase in biochemical research, cell culture medium additive, raw material for in vitro transcription kits, and liposome formulation research.

Q2: What is the difference between CDP disodium salt CAS 54394-90-0 and CDP trisodium salt?

They differ significantly in sodium ion count, molecular weight, aqueous pH, and synthesis routes, meaning they cannot replace each other.

  • CDP Disodium Salt: Exclusively optimized and used for citicoline industrial synthesis.
  • CDP Trisodium Salt: Primarily applies to partial academic enzyme research. Using it in pharmaceutical condensation steps leads to inconsistent reaction yields.

Q3: How to choose the correct purity grade CDP-Na₂ for my production?

Grade 1: ≥98% Biochemical Grade
Best for academic labs, routine cell culture, and standard enzyme testing.
Grade 2: ≥99% Pharma Intermediate Grade
Tailored for Citicoline drug manufacturers and standard GMP production lines.
Grade 3: ≥99.5% High-Purity Reference Standard
Ideal for NMR spectrum calibration, new drug R&D, and diagnostic kit raw materials.

Q4: Why does CDP disodium salt agglomerate easily after opening the packaging?

CDP-Na₂ possesses strong hygroscopicity. Water molecules in the air quickly break the pyrophosphate bond, leading to caking, agglomeration, and subsequent chemical degradation. Action Required: After opening, seal immediately with a desiccant, store at low temperatures, and consume within 6 months.

Q5: Can I ship CDP disodium salt by sea freight without a cold chain?

Short-distance shipments: Under mild seasonal temperatures (below 25°C), standard shipment is acceptable provided the fiber drums are fully vacuum-sealed.

Tropical/Summer shipments: Long-distance sea freight during hot seasons requires cold-chain packaging (with ice packs) to proactively prevent moisture absorption and hydrolysis during transit.

Q6: What supporting documents can your factory provide for customs clearance?

We provide a comprehensive documentation package to ensure smooth global customs clearance:

⚠️ Stability & Structural Warning for Logisticians:
A critical structural feature is the pyrophosphate linkage in its molecular chain. This high-energy bond supports CDP-Na₂ to act as an activated carrier molecule inside biochemical pathways, yet the same bond breaks down under high heat, strong acid, or prolonged air exposure. Unlike monophosphate cytidine (CMP) or triphosphate cytidine (CTP), CDP disodium salt contains exactly two phosphate groups, matching the precise structural requirement for citicoline condensation production. Its strong water absorption capacity means qualified suppliers must adopt vacuum aluminum foil packaging and cold-chain delivery.

2. Industrial Commercial Applications of High Purity CDP-Na₂ for B2B Buyers

The industrial utility of cytidine 5′-diphosphate disodium salt segments clearly across high-volume production lines and precision laboratory applications:

🏭 Mass Production of Citicoline

In the classic Kennedy lipid synthesis pathway, CDP-Na₂ condenses with phosphocholine under specific enzyme catalysis to generate finished citicoline raw materials. Citicoline (CDP-choline) is a mainstream clinical neuroprotective drug used to treat brain injury, stroke sequelae, and cognitive decline disorders. Pharmaceutical manufacturers with GMP lines require consistent, low-endotoxin CDP disodium salt with HPLC purity above 99% to comply with global drug registration standards.

🔬 Laboratory & Diagnostic Biotech R&D

It serves as the exclusive specific substrate of CDP nucleoside diphosphate kinase, converting CDP into CTP to fuel advanced DNA and RNA synthesis research. Ribonucleotide reductase testing, cell culture medium formulation, and liposome drug delivery system development all rely heavily on stable batches. Furthermore, diagnostic kit manufacturers add CDP-Na₂ as a core reaction substrate for in vitro enzymatic detection reagents.
