Schircks Laboratories, Switzerland was founded by Dr. B. Schircks in 1980 to synthesize pteridines. The company is independently owned and operated. Schircks Laboratories has ceased production of tetrahydrobiopterin. Biomarin has taken over the US market and Merck Serono the European market. They will continue to expand. They are responsible for the supply of tetrahydrobiopterin (Sapropterin dihydrochloride) in tablet form (Kuvan).

Over 100 other pteridines are synthesized by Schircks Laboratories which are mainly used in science and clinical diagnostic applications. We are constantly developing and improving syntheses and starting new syntheses to meet the demands of research and development groups worldwide.

schircks 11.420说明书

6-Hydroxymethylpterin 

Product no. 11.420 

Abbreviation: HMP 

CAS No.: 712-29-8

说明黄色粉末

生物化学6-羟甲基蝶呤是四氢叶酸合成的中间体。

溶解性6-羟甲基蝶呤几乎不溶于水。非常轻微

可溶于0.01 M NaOH。pH值约为11.0，（约为0.07 g/100 g 0.01 M

氢氧化钠（22摄氏度）。柱水Spherisorb S5-ODS 2，4.6 x 150 mm洗脱液10 mm Na2HPO4 pH 7:乙腈，39:1流速1 ml/min波长215 nm

分析方法

高效液相色谱

条件

溶液1 mg/3 ml 0.01 M NaOH

纯度：HPLC>97.5%

稳定性6-羟甲基蝶呤对光敏感。它不吸湿。在室温下储存3个月的粉末是稳定的，在这一时间之后，通过HPLC分析，其纯度没有变化。HMP在0.01M NaOH中的1mM溶液在室温下仅略微不稳定，在室温下储存7天后，HPLC分析显示降解率为6%。

在-20°C或更低温度下，将粉末保存在小瓶中保持干燥。HMP可以在不使用干冰的情况下运输。

使用HMP是分析工作的重要标准。我们的产品仅供实验室使用。安全HMP是安全的，在处理本产品时不需要特别的预防措施。

Tetrahydrofolic acid

Product No.'s 16.207-16.209

(6R,S)-5,6,7,8-Tetrahydrofolic acid trihydrochloride (R/S ratio ≈ 1:1)

Product no. 16.209 6R,S-FH4x3HCl

CAS No. [135-16-0]C19H23N7O6x3HCl

MW 554.8

叶酸的化学还原产生两种非对映异构体6R-和6S-FH4。6S-FH4是四氢叶酸的天然形式。
（6S）-5,6,7,8-四氢叶酸和（6S）-5,6,7,8-四氢叶酸三盐酸盐的6R非对映异构体含量低于0.6%。

说明：米色粉末。
生化功能叶酸本身没有生物活性。它被转化为四氢叶酸，四氢叶酸是人体内一种重要的辅酶。这进一步反应形成甲酰基、亚甲基、亚甲苯基和甲基四氢叶酸，这些四氢叶酸反过来负责转移自然界中的碳片段。
溶解性6R、S-FH4x3HCl和6S-FH4x3HCl可自由溶于水。其溶解度至少为40 g/100（22°C）。1mM 6R，S-FH4x3HCl水溶液的pH值为2.67。产品编号16.207是一种游离酸
几乎不溶于水。10mg 6S-FH4可溶解于10ml 0.01N NaOH中。

纯度：HPLC 95.0%-98.0%
必须在分析前立即制备FH4溶液（另见：稳定性部分）。
添加DTT可改善结果（0.75 mg/ml洗脱剂）。
稳定性在-20°C的安瓿中干燥，FH4是稳定的。它在溶液中非常不稳定。在室温下，它与氧发生反应，尤其是在中性或碱性溶液中。
溶液应尽可能浓缩在无氧水中，pH值尽可能低，并立即使用。
在溶解过程中，这种物质迅速降解。即使在室温下打开1mm6R 5分钟后，S-FH4x3HCl溶液的降解率也超过10%。45分钟后，其降解率约为25%。
将粉末保存在-20°C或更低温度的安瓿中。打开安瓿后，剩余的安瓿应保存在紧闭的小瓶中，放在冰箱中。
安瓿中的四氢叶酸可以在不使用干冰的情况下运输。在安瓿中干燥，在室温下稳定数周。
FH4是分析工作中的一个重要标准，在生长中的儿童和孕妇的饮食中也很重要。我们的产品仅供实验室使用。
安全信息由于四氢叶酸的酸性，应避免长时间吸入四氢叶酸。否则，在处理本产品时不需要特殊的预防措施。

生物蝶呤的化学还原产生两种非对映异构体6R-和6S-BH4。6R-BH4是四氢生物蝶呤的天然形式。我们生产的6R，S-BH4含有约70%的6R-BH4和30%的6S-BH4。

生化功能四氢生物蝶呤是芳香族氨基酸羟化酶的天然辅因子，参与酪氨酸、神经递质多巴胺和血清素的合成。它也是一氧化氮合酶催化L-精氨酸氧化为乳酸菌素和一氧化氮所必需的。四氢生物蝶呤参与许多其他生化功能，其中许多功能是最近才发现的。
溶解性6R-和6R，S-BH4x2HCl可自由溶于水。6S-BH4H2SO4的溶解度为2.3 g/100（22°C）。
1mM的6R-BH4水溶液的pH值为3.0，1mM的6R-BH4水溶液的pH值为0.45。

纯度11.212号产品纯度>99.5%，6S-BH4含量低于0.1%，不含氯化钠。
稳定性四氢生物蝶呤非常吸湿。
它与氧发生反应，尤其是在中性和碱性溶液中。由于氧化，四氢生物蝶呤溶液变黄，但在-20°C或更低温度下，溶液相对稳定。
0.1 mM四氢生物蝶呤水溶液的稳定性远低于1 mM溶液，即在室温下打开1小时后，0.1 mM溶液降解约25%，而1 mM溶液仅降解2%。3小时后，0.1 mM溶液的降解率超过60%，1 mM溶液的降解率仅为10%。
干粉的稳定性因条件而异，如下表所示。RT-20°C在安瓿中放置数月或数年
装运期间未控制储存条件，我们无法保证客户将在6周内收到货物。安瓿在室温下稳定数月，因此在邮寄过程中延迟使用时，无需担心。过去购买过6R-BH4的客户可以估计装运所需的时间。
到达时，我们建议将粉末储存在-20°C或更低温度。打开安瓿后，应将剩余的安瓿放入小瓶中，然后将其储存在冰箱中。
四氢生物蝶呤溶液应在pH值尽可能低的无氧水中制备，并尽快冷冻。为了提高BH4溶液的稳定性，可以添加抗坏血酸、DTT或其他抗氧化剂。
安全信息四氢生物蝶呤在预期用途中是安全的。避免长时间吸入酸性很强的四氢生物蝶呤细粉尘。否则，在处理本产品时无需采取特殊预防措施。
