产品说明 应用 胞嘧啶已用于： - 制备碱基溶液
- 作为高效液相色谱(HPLC)标准品
- 估算全基因组甲基化水平
- 核苷5′-三磷酸(NTP)合成
- 纯化
包装 1, 5, 10, 25, 100 g in poly bottle 生化/生理作用 胞嘧啶(C)是DNA和RNA中发现的四种主要碱基之一，其他三种为腺嘌呤、鸟嘌呤和胸腺嘧啶(RNA中的尿嘧啶)。
胞嘧啶是一种嘧啶，与鸟嘌呤碱基对形成三个氢键。它可形成胞嘧啶核苷酸，进一步可磷酸化为胞嘧啶5′单磷酸(CMP)、胞嘧啶5′二磷酸(CDP)和胞嘧啶5′三磷酸(CTP)。 基本信息 | 经验(实验)分子式 | C4H5N3O | | 分子量 | 111.10 | | Beilstein | 2637 | | EC 号 | 200-749-5 | | MDL编号 | MFCD00006034 | | PubChem化学物质编号 | 24892620 | | NACRES | NA.51 |

产品说明 一般描述 Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. 应用 These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Cytosine may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by capillary zone electrophoresis and chromatography techniques. 分析说明 These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available. 其他说明 This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis. 附注 To see an example of a Certificate of Analysis for this material enter LRAA1102 in the slot below.
